SPECIFICATION forming part of Letters Patent No. 794,015, dated July 4-,1905.

Application filed May 4;, 1905. Serial No. 253.877.

To m/l Iv/toot i/z 11m concern:

lite it known that i. FEEDING J ussn llUS'ltlP- Lee, a citizen of theUnited States, residing at ltllnlvane, in the county of tlumner andState ol liansas, have invented new and useful lmprovenu-nits inBoiler-(jleaners, which the l' ,)llowine' is a speci lieation.

l rlly invention is a boilcr-clcaner of that type comprising a chainhearrangtal outside the boiler thmue'h which the water circulatesand inwhich the scale and other impurities are precipitated.

The object of the invention is to provide an apparatim of this kindembodyiiig siniplicity ol eonstrllction and thorough etliciency oloperation.

in the accompanying' drawings, .lliigure l is an elemtimi of a boilerwith my appzu'atus in position. Fig. 2 is a longitijulinal sectionalview of the apparatus. Fig. 3 is atransverse sectionon the line 3 3 ofFig.

litelerrine specifically to the drawings, dc notes a boiler which may beof any construction or type, nothingbeing claimed with respect thereto.The precipitation-chaml)er is indicated at b and is provided withadepending branch 7. ilnside the chamber (:3 is a vertically-arrangedballle-plale 8, which extends to the side walls of the chamber, but isspaced from the top and bottom thercol, the top space [J beingnarrow andthe bottom space 10 wide.

at or about the middle ol the chamber (3 is a horizontal iartition 11,which extends from one end of the chamber to the ballle-plate, beingsecured to the latter. The partition is spaced, sliglitly from the wallsoi the chamber for a purpose to be hereiiialter (lescrilmd.

An i1ilet-pi e l2 enters the front end ol' the chzunber (3. Theoutlet-pipe 13 extends from top ol the chamber,near the rearcnd thereof,above the partition 11. The inlet-pipe extends into the boiler justbelow the water-line, and the outlet-pipe enters the lowest part of theboiler, so that there is a continuous circulation of water through thechamber. The

lower end of the branch 7 is litted with a blowotl pipe 14. l

The operation of the ammratus is as tollows: The water entering theehanil ierfi strikes the bafiie-nlate h, which retards its [lowsomewhat, causi no the scale, di rt, &c., to he preci pitated and topass under the ballle plate through the space 10 into thebranch 7. whereit collects and from which it can be blown when nmlessary through theblow-oltpipe lei. As the partition 1 l is slightly spaced from the walls01 the clutmber, there will be sullicicnt circulation under thepartition to carry the impurities to the lHftHCll 7. 'lhere is, however.no circulation in the latter, and the impurities collecting therein willnot agijth'i be taken up by the water to be passed into the boiler. Theclear water iassesover the battleplate through the space 9 and out olthe chamber and back to the boiler tl'irough the outletpi :)e 1.3.

li'l aving' thus described my invention, what is claiined as new, anddesired to be secured by Letters Patent, is

1. The coml iination with a boiler; 01 a precipitation-chanther, havinga (ilepending branch, and an inlet from the boiler; a ballle-plate inthe chamber between the inletand the branch, and spaced from the top andbottom of the chamber; an outlet to the boiler behind the balile-plate;and a partition in the chamber between the branch and the outlet.

2. Thec m1bination with a boiler; 01' a precipitation-cliamber having asedin1ent-collection receptacle; an inlet from the boiler; abafil'llcplate in the clntniiber between theinlet and the receptacle,and spaced from the topand bottiinn oi the chalnber; an outlet to theboiler lashind the batlle-plate; and a partition in the chainber betweenthe receptacle and the outlet.

In testin'iony whercol ll havesigned my name to this specification inthe presence 01' two sub scribing witnesses.
